IRAS Scan Processing and Integration tool


Scanpi Software Tool Operational

Scanpi is an interactive software tool for viewing, plotting and averaging the calibrated survey scans from the Infrared Astronomical Satellite (IRAS); these scans are the fundamental data from the IRAS survey. Scanpi is useful for measuring the fluxes of extended, confused or faint sources, for diagnosing source extent, and for estimating local upper limits. The sensitivity gain as comparable to that obtained in the IRAS Faint Source Survey is about ¾, or about a factor of 2-5 over the IRAS Point Source Catalog (PSC), depending on the local noise and number of scans crossing the target position. Scanpi allows users to interactively subset, plot and coadd IRAS scan data at any sky position. Source lists can also be uploaded. Scanpi is intended for immediate access to the basic IRAS data for users wishing to process positions interactively.
